Cylinder Silencer

Cylinder Silencer is the acoustic patent equipment designed and has undertaken engineering applications for many years. (Patent No. ZL 2008 2 0091148.0).

The external hollow cylinder and internal acoustic cylinder cartridge constitute the whole cylinder silencer structure. The external hollow cylinder is made of boiler steel and covered by thermal insulation at inner side.  Inner insulation layer is filled with efficient acoustic pillow (aluminum silicate and rock wool with resistance to high temperature) wrapped by silicon oxygen cloth. The cover plate is made of stainless steel punching plate and connected to external cylinder by expansion bolting. The design of overall structure has taken into account the thermal expansion and resulting stress. The internal cartridge has the same configurations with external surroundings as above in surface cover plate, acoustic filling and packaging. The space between external cylinder and internal cartridge is reserved for the ventilation of high temperature air flow.

The cylinder silencer is suitable for applications in areas with high corrosive salt, fog, damp or sea. At each ends of the cartridge, structural sections are used as a support by expansion connection to external cylinder. The cross-section diameter of cylinder cartridge is determined by different noise level of the air flow. The shape of both ends of the cartridge is designed on the basis of air dynamic theory. The total lifetime can be prolonged up to 20 years.

There are two major cylinder silencer models: CLDD45 and CLDD65 with the noise reduction of 45 dB(A) and 65dB (A) respectively on the low and middle frequency spectrum.( the exact acoustic attenuation shall be calculated by weight due to frequency spectrum). Particularly, customized retrofit is also available to change technical parameters of cylinder silencer

CLDD cylinder silencer has low pressure drop, low cost, long durability and robust noise attenuation capability on the low frequency spectrum. Therefore, it becomes the primary choice for acoustic engineering applications in high temperature exhaust/outlet system. Besides, the implementation of boiler steel has well known benefits on suppressing material cost. Similarly, the selection of CLDD cylinder silencer in construction engineering is rewarded with space saving advantage in structure erection. 

It should also be noted that Cylinder silencer is only suitable for situation where the flow rate of high temperature air does not surpass 100 kg/s and the exhaust/outlet ducting has better to be long in favor of substantial cost reduction because silencer cartridge could be arranged right in the middle of ducting. 

Application
CLDD 45/65 cylinder silencer is suitable for various acoustic silencing applications within temperature ranging from -40℃to 600℃and would not be inflicted any limit on length. Stainless steel shall be selected as silencer material under working conditions at sea, onshore, damp or acid rain regions, otherwise galvanized plate turns out to be an alternative option for applications in dry continental area.

Acoustic engineering instances including Gas turbine exhaust, diesel generator exhaust, and naval ship exhaust noise reduction have altogether demonstrated its high competence and explicit advantage.

The cylinder silencer has the advantages of low frequency, high noise reduction level, low flow resistance, low cost and long service life, which can be applied in the temperature range from -40℃to 600℃ in various fields. There is no limitation in the lengthwise direction. The cylinder silencers designed for application in the oceanic, coastal, wet, acid rain environments are made of stainless steel, and those designed for application in dry inland regions are made of galvanized sheet. The cylinder silencer is also quite suitable for complete sets of equipment in the exhaust system.

Apply to the equipment:

  • Blower, Axial blower
  • Boiler
  • Aviation Testing bed
  • Ship power system
  • Air compressor
  • Air conditioner
  • Backup power system
  • Mineral ventilation
  • High temperature equipment
  • Centre air conditioner of Hotel, building
  • Subway ventilation
  • Kitchen ventilation

 

There are different sound spectrum among different equipment, different power, or different manufacturer brand.

The following data are the reference based on the experience. The accurate test data will be tested in the real life of operation, which is used to reduce the cost and select the most suitable silencer.
